Abstract
A kind of chain link Rung press process, including following operating procedure；Step 1, the arc surface contacted to crosspiece both ends with ring body before pressing shelves are sanded, until any burr or protrusion is not present；Step 2 is polished with crosspiece contact site after deburring, before pressure shelves on the inside of ring body, and the defects of folding or crackle are generated in impression is avoided；Step 3, operator clamps crosspiece using pliers and places it in ring body center when pressing shelves, the temperature of chain link when shelves are pressed in control, and passes through debugging and shelves machine is pressed to obtain the ring length and ring width for meeting drawing requirement, and record mold stroke is simultaneously limited accordingly；Crosspiece offset, inclination, the problems such as impression is uneven can be effectively prevented in the present invention, can obtain that position is accurate, crosspiece impression of uniform depth in the case where meeting chain link overall dimensions, reach the requirement of specification.
Description
Technical field
The present invention relates to the field of chain link more particularly to a kind of chain link Rung press process.
Background technique
Anchor chain is outfititem important on ship, is mainly used for the anchoring of ship；Grade ring be in anchor chain using the time most
Type long, purposes is most wide, primary structure are the crosspieces in one dumbbell shaped of ring body center insertion of ellipse.The peace of crosspiece
Dress can be effectively improved the stress distribution of oval ring body, the service life of chain link be improved, to provide the overall performance of anchor chain.
Crosspiece is mainly made by way of hot pressing, and when chain processed, chain ring body passes through induction heating, bending, welding, deburring
Etc. after processes, crosspiece is pressed into the case where certain heating temperature, then can be as needed to crosspiece edge using welding
Form is reinforced, that is, forms stud link chain ring.Since shape, position and the depth of crosspiece indentation can generate weight to the performance of chain link
It influences, therefore guarantees to press shelves quality by series of process control measure.
Summary of the invention
It is an object of the present invention to provide a kind of chain link Rung press process, and method is simple, easy to operate, guarantee the performance of chain link, solution
It has determined the above technical problem.
In order to achieve the above technical purposes, reach above-mentioned technical requirements, the technical scheme adopted by the invention is that: it is a kind of
Chain link Rung press process, it is characterised in that: including following operating procedure；Step 1 contacts crosspiece both ends with ring body before pressing shelves
Arc surface be sanded, until be not present any burr or protrusion；Step 2, after deburring, before pressure shelves, on the inside of ring body with
Crosspiece contact site is polished, and the defects of folding or crackle are generated in impression is avoided；Step 3, operator uses when pressing shelves
Pliers clamps crosspiece and places it in ring body center, the temperature of chain link when shelves are pressed in control, and obtains satisfaction figure by debugging pressure shelves machine
The ring that paper requires is long and ring width, record mold stroke are simultaneously limited accordingly.
Preferred: the temperature of chain link when pressing shelves is controlled at 400 DEG C -700 DEG C.
Preferred: the chain link two sides stretched position temperature difference is no more than 200 DEG C when pressure shelves, and the higher side of temperature can pass through compression
Air or other modes are cooled to defined temperature range.
It is preferred: positioning device is provided on the pliers to control crosspiece position.
Beneficial effects of the present invention；A kind of chain link Rung press process by control crosspiece surface quality, pressure shelves temperature, is clamping
Positioning device is set on son, the problems such as crosspiece is deviated, tilted, impression is uneven can be effectively prevented, chain link entirety can met
It in the case where size, obtains that position is accurate, crosspiece impression of uniform depth, reaches the requirement of specification；Suitable for batch production.
Specific embodiment
In order to be more clear goal of the invention of the invention, technical solution and its advantageous effects, below in conjunction with specific
Embodiment, the present invention will be described in further detail；
A kind of chain link Rung press process, it is characterised in that: including following operating procedure；Step 1, before pressing shelves to crosspiece both ends with
The arc surface of ring body contact is sanded, until any burr or protrusion is not present；Step 2, after deburring, before pressure shelves, to ring
Internal side is polished with crosspiece contact site, avoids the defects of folding or crackle are generated in impression；Step 3 operates when pressing shelves
Personnel clamp crosspiece using pliers and place it in ring body center, the temperature of chain link when shelves are pressed in control, and are obtained by debugging pressure shelves machine
The ring length and ring width that drawing requirement must be met, record mold stroke and are simultaneously limited accordingly.
The temperature of chain link when pressing shelves is controlled at 400 DEG C -700 DEG C；The chain link two sides stretched position temperature difference is not when pressing shelves
More than 200 DEG C, the higher side of temperature can be cooled to defined temperature range by compressed air or other modes；The pincers
Positioning device is provided on son to control crosspiece position.
Specific implementation of the invention: the arc surface contacted first to crosspiece both ends with ring body before pressing shelves is sanded, directly
To there is no any burr or protrusions；Then it is polished with crosspiece contact site on the inside of the ring body of chain link, is avoided in impression
The defects of generating folding or crackle；It is disposed and carries out pressure shelves again, operator is pressed from both sides using the pliers with positioning device when pressing shelves
Firmly crosspiece places it in chain link ring body center, and the temperature setting of chain link is 400 DEG C when pressing shelves, and ensures chain link two sides stretched position
The temperature difference is no more than 200 DEG C, and the higher side of temperature can be cooled to defined temperature range by compressed air or other modes；Most
The ring length and ring width for meeting drawing requirement are obtained by debugging pressure shelves machine afterwards, mold stroke is recorded and is limited accordingly；Crosspiece
Compression distance is 0.02d ~ 0.06d, and wherein d is the nominal diameter of chain link.
Using the Rung press process, the service life of chain link is improved, enhances the overall performance of anchor chain；It effectively prevent crosspiece
Offset, inclination, the problems such as impression is uneven can obtain that position is accurate, uniform depth in the case where meeting chain link overall dimensions
Crosspiece impression, reach the requirement of specification；During pressing shelves, the temperature of chain link may be arranged as 500 DEG C, 600 DEG C or
700℃。
Above-described embodiment is only intended to clearly illustrate description made by the present invention, and does not limit the embodiments,
To those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
Dynamic, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation or change thus amplified out
It is dynamic to be still in the protection scope of this invention.
